Genie, I love the idea of the rhythmic arrangement and can imagine Barry himself beating the bodhran on it. You do it in any way you want. Bend it, change it, add, subtract. If you feel moved, take the basic idea and write an entirely new song even.
Most of you know a hell of a lot more about shanties than I do. I think Barry would dig hearing this in all it's iterations. And somehow, I get a sense that he'll be there when any of us do it, as long as we pour heart and soul into it, just like he did in every song I ever heard him do. I give this song to him and to anyone else who sings it. If somebody makes a fortune with it, we can talk ;>).

One thing I would love to hear though. I'd love to hear Ken Schatz do some form of this next Getaway, God willing we all meet there again. I think Ken's energy comes from the same blazing fire where Barry got his.
